Hekla volcano (Iceland): strong inflation suggest volcano could be close to erupting

The famous Icelandic volcano is showing further signs that indicate an eruption could occur in a near future. Significant rapid inflation, concentrated in the northern part of the volcano, has been detected since early April and likely represents accumulation of rising magma underneath.

Already in mid March this year, an earthquake swarm, volcanic tremor and deformation caused an alert, because it was believed that this was caused by rapid movement of magma under the volcano.
The last eruption of the volcano was in March 2000, and it is estimated that by now, a significantly larger volume of magma has since then accumulated beneath the volcano. This would mean that a new eruption should be expected to be larger than the last one. Hekla's eruptions normally begin with a powerful explosive phase, and could pose a significant hazard to anyone in close (less than 10 km) proximity during the onset of it.

The Icelandic Meteorological Office has informed authorities about unusual seismicity at Hekla volcano, which could be a precursor to a new eruption, and increased the volcanic alert level to yellow. Monitoring of the volcano will be intensified, as Hekla is not only one of the most active, but also one of the potentially most hazardous volcanoes of the country. The last eruption was in March 2000. On average, the volcano has been erupting about every 10 years, and it would statistically seen be due for a new one. ... [more]

Small earthquakes continue to occur around and beneath the volcano. At the moment, it does not seem a significant increase and we have no other data suggesting that the volcano should erupt soon (although it very well could). [more]
